Answer» Correct Answer - Option 1 : 6 Given: The digit present in place of the unit of the cube root of a number is equal to the digit present in place of the unit of its number. Calculation: We have unit digits in any number from 0 to 9 Let us cube the unit digit and see how many of the cubes so obtained will have the same unit digit.
From the above table we get that in 6 numbers, the unit digit of the cubes is the number itself. ∴ The required answer is 6. |
